There is a movement in Cinema to acquire content at resolutions and gamuts that far exceed the need of the end result. (RED just announced their new 6K sensor at NAB.) They have plans to create a 28K sensor:

Is brighter better? I think the goal of any great motion picture maker is to create the highest quality story coupled with the highest quality production.

But very few pay attention to the distribution medium. Douglas Trumbull was recently honored by the Academy for his contributions to the science of motion pictures. He was citing this very fact, calling out studio executives who spend massive budgets on VFX and such only to see it watered down when the lights go down. So much time and energy is poured into production tech (which he think is great) but very little is done for quality assurance when it actually hits the projection booth. In his research he has show that the majority of the cinematic world knows very little about projectors. This includes theatre chains.

James Cameron and Peter Jackson are taking up his passion of highest fidelity end to end. They are pioneers of cinema trying to move the industry forward to higher quality standards.

This does mean that everyone has to up their game. It's year one in cinema. Middle Earth is New Zealand!
